The short answer
If you want the cleanest Palworld 1.0 experience, a new save is usually the safest choice. If you are attached to an existing world, wait for official compatibility notes and back up everything first.
This is not a claim that old saves will or will not work. It is a practical recommendation for avoiding launch-day frustration.
Reasons to start fresh
- You want to experience any updated early-game pacing naturally.
- You are returning after a long break and need to relearn systems.
- Your old world has outdated base layouts or mod history.
- Your group wants everyone to progress together from day one.
Reasons to continue an old world
- You have builds, collections, or multiplayer memories you care about.
- Your server group mainly wants to explore new content from an established base.
- You are willing to troubleshoot if old assumptions conflict with 1.0 changes.
Best compromise
Keep your old world backed up, then make a short fresh save for the first few hours of 1.0. After the patch notes and early stability reports are clear, decide whether to continue fresh or return to the old save.
